Customized Lift-Type Straight Seam Automatic Welding Machine Technical Solution

Introduction To Automatic Straight Seam Welding Machine

The liftable straight seam automatic welding machine is used to complete the straight seam welding of cylindrical stainless steel, galvanized sheets, carbon steel and other metal materials.

An automated welding system designed for line welding. This machine has high working efficiency, easy operation and is suitable for mass production. Department

The system consists of welding machine tools, straight seam welding control systems and welding power sources. This equipment uses a fixed workpiece and a moving welding gun.

way to complete the welding.

Advantages of this equipment:

1) Provide stable and continuous compression and cooling effects in the entire weld direction, reducing the welding heat-affected zone and post-weld deformation

shape.

2) The overall structure of the cantilever and beam of this equipment can be lifted electrically, and pulleys are installed at the bottom. Compared with traditional fixed

The fixed bed has a larger processing diameter range, making workers’ operations more convenient and labor-saving, and improving efficiency.

3) Ensure the dimensional accuracy of the welded products by reducing welding deformation and shrinkage.

4) The bushing ensures the forming effect on the back side, and better surface quality can be obtained through front and back protection.

Seam Welding Machine Main Structures

The entire equipment adopts a cantilever structure, with a welding execution system attached to the crossbeam installed on it. The welding execution system follows a straight line

The guide rail moves smoothly in a straight line and at a constant speed, and is dragged by the motion mechanism. The welding gun regulator is installed on the linear guide rail to complete the movement.

Welding process of paired work pieces. This equipment uses a pneumatic compression clamp to ensure that the butt joints are compressed within the welding length. Book

The equipment has optional functions such as simulation and actual welding.

A brief introduction to the main structure of the machine tool:

2.1. Pressing mechanism

It adopts a pneumatic pressing structure. The pneumatic pressing structure provides downward pressure along the entire length of the weld. The pressing mechanism can ensure that the joints fit well before welding.

The main shaft of the straight seam welding machine supports the work piece, and the pneumatic pressing mechanism drives the work piece to be pressed. The welding trolley moves along the straight

The linear guide rail moves smoothly in a straight line and is dragged by the motion mechanism. The welding gun regulator is installed on the linear guide rail to move.

Complete the welding process of the work piece.

Opening and closing the door: When loading and unloading materials, it is in a lifted state. Before the pressing mechanism is pressed down, rotate it downwards and hang it on the right side of the mandrel to ensure

There will be no disturbance when the mandrel is pressed.

Lining: There is a copper lining on the mandrel, a forming groove is processed on the copper lining, and a protective air hole is processed on the bottom.

A series of small holes communicate with the formed groove on the front side of the bushing on the back side of the weld. Ensure the forming and heat dissipation during work piece welding and work piece welding

Seamed back protection.

2.2. Welding gun traveling mechanism

It is used to realize the automatic welding process of the welding gun, with high transmission precision, adjustable moving speed, and automatic idle and rapid return. weld

The connecting car moves along a straight line, and the linear motion guide rail adopts precision linear square rail, and the motion trajectory has good straightness. Traveling gear motor

It has large starting torque and excellent output characteristics. The maximum welding length of this machine reaches 1500mm.

2.3. Welding gun lifting mechanism

This machine controls the pneumatic actuator through the program to automatically raise and lower the welding gun. The welding gun can be adjusted in the welding position through the gun adjuster.

section, by adjusting the welding position, the welding gun can be in a better welding position. The adjustment in the vertical direction is mainly to adjust the end of the welding gun

The distance between the head and the work piece sets the length of the welding arc and establishes the voltage of the welding arc. Horizontal and lateral adjustments are mainly

Adjust the welding gun tip to align with the seam.

2.4. Electrical control system

The whole machine control adopts PLC programmable controller to realize a series of automatic positioning of the welding gun, automatic welding, automatic return, etc.

Automate actions and simulate and demonstrate process parameters.

The equipment has a “manual/automatic” conversion function. In the “manual” state, the welding machine does not arc, and can adjust the welding speed,

A series of process parameters such as welding length and welding position can be adjusted, and the “automatic” state can realize the automatic welding process. Other,

The welding length of the work piece can be adjusted according to needs.
